What is the Difference Between Dry Bulb and Wet Bulb Temperature?

Show all

One of the most important factors in determining the effectiveness of evaporative cooling is the delta–the wet bulb depression- between the dry bulb and the wet bulb temperature. The dry bulb temperature is the ambient air temperature that is measured by regular thermometers, while the wet bulb temperature is measured by thermometers that are wrapped in wetted wicks. The greater the wet bulb depression, the greater the felt effect is on the discharge air temperature. In ideal operating conditions, using Cel-Air® equipment along with a high quality evaporative cooler media,  evaporative cooling systems are able to lower the sensible heat of the air by 80 to 90 percent of the wet bulb depression.
